To all whom z5 may concern:

Be it known that l, GRANVILLE H. STALL- MAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hog-scraping Machines, of which the following is a specification.

This invention relates to improvements in hog scraping machines, and one of the objects of the same is to provide improved mechanism whereby the carcass will be regularly fed through the machine and intermittently rotated during such feeding movement, all of the parts of the carcass being subjected to the actionof the cleaning elements which are continuously in contact with the carcass and move thereover with a wiping action.

A further object is to provide an improved machine of this character having automatically adjustable cleaning elements which engage and remain in Contact with the surface of the carcass, and which elements are adapted to compensate the va rying sizes of the carcass, the speed of ro tation of the cleaning elements about the carcass increasing in proportion to the size of the carcass.

To the attainment of these ends and the accon'iplishment of other new and useful objects as will appear, the invention consists in the features of novelty, in substantially the construction, combination and arrange ment of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating the invention and in whichh i Figure 1 is a front end elevation of an improved machine of this character embodying the principles of this invention. y

Fig. 2 is a side elevation taken from the left hand side of Fig. 1.

Fig. 3 is an enlarged detailsectional view taken on line 3-3, Fig. 1.

Fig. 1 is an enlarged detail sectional view taken on line 4-4, Fig. 3.

Fig. 5 is a horizontal sectional view taken on line 5-5, Fig. 4:.

Fig. 6 is a vertical sefional view taken on `line 6-6, Fig'. 3,

Fig. 7 is a sectional view taken on line 7-7, Fig. G and with parts omitted.

Referring more particularly to the draw* ings, the numeral l() designates a suitable supporting structure arranged at any snitable elevation and upon which structure is mounted a cleaning mechanism. rlfhe cleaning mechanism comprises a series of annular elements 11 which may be of any desired size and are spaced laterally from each. other to permit a series of annular elements 12 to be arranged therebetween.

The elements 11 are supported in any desired or suitable manner, preferably by means of a series of rollers 13 preferably provided with laterally projecting flanges 14 arranged a short distance inwardly from the periphery 15 of the roll, and the flange 111 is adapted to be engaged by an annular flange 16 on theelement 11 so as to hold the element in position. The elements 12 are each supported by a series of rolls 17, similarly constructed and having a laterally projecting flange 13 cooperating with a flange 19 on the outer periphery of the annular member' 12. The respective pulleys 13, 17 are arranged in alinementwith each other and are all preferably loosely mounted upon an axle 20 having suitable bearings 21 in the frame l0, l

The elements 11. are of a diameter somewhat greater that the diameter of the elements 12, so that when the elements are as sembled in alinement with each other, the elements 11 will be supported eccentrically with respect to the`elements12 so that when the carcass is being fed through the elements 11, 12 in a manner to be hereinafter set forth, the elements 12 will serveas the supporting elements to hold the carcass up and out of engagement with the lower portion of the elements 11 so that an undue strain will not be placed upon the Scrapers during the passage ofthe carcass through the ma chine as will be hereinafter set forth.

Each of the elements 12 is provided with a peripheral gear 22, with which a driving gear 23 meshes so as to rotate the elements 12 and these driving gears 23 are themselves rotated by means of a shaft 24 with which is connected a pulley 25 for rotating the shaft,

The elements 11 are also provided with peripheral gear teeth 26 with which a gear 27 meshes and theV gears 27 are connected with a shaft 28 that receives its motion from a pulley 29, and the gears 23, 27 are so rotated a suitable sprocket 35 and a sprocket 3G, the

latter operating the pulley 37 over which the @caterer 31 passes- As the carcass iselevated from the tanl; 30, it is fedy into the machine through the Y opening 38 in the front of the frame 10 and is delivered'into the front element 1 2. Arranged within the elements 12 are spirally disposed projecting ribs which extend inwardly fromthe periphery of the annular lmember and gradually increase in height throughout the `length of the rib and the ribs are arranged to -extend partially around the element.

c These Lribs 39 ycatch the carcass as it is fed into the element and advance the same therethrough so that it will extend across the element 11 and project into the next successive element 12.

All of the -elements 12 with the exception of the foremost element are provided with inwardly projecting ribs et() which are spaced from each other in a direction extending around thercircumference of the member,

y the ribs 40 extend transversely of the ribs 39 and o-perate intermittently to rotate the carcass during its advancing movement through the elements. The ribs L10 are omitted from the first element 12 because, when-the carcassis first `.placed in the ma- I chine, it is not necessary to rotate it, Vbut as it is advanced through the machine it is intermittently rotated by these ribs.

Thescraper elements 11 are provided with scraper members (L11, shown more particularly in Figs. 3 and 6, and whichV members arepivotally supported b-y suitable bearings 112, andthe body portion of the members 41 arezarranged'within the element 1 1 and are preferably curved in a direction extending'V around the circumference of the element.

yriprese,members 411 may beV of any desired length and Secured thereto are scraper blades Vi'which may be of any desired size and configuratien and are removably secured to Vthe member 41 in any suitable manner, and

are 'spaced laterallyfroni each other and in adirection extending lengthwise ofthe memberf 41, -bysuitable spacing members 43a. rlhe member-111 is provided with an arm 411i which projects therefrom beyond the pivot 4.2 andthrnugh a suitable opening 45 inthe @lenient 12mths Outside there-0f, and .GQ11- nected to the arm 1i adjacent the outer periphy of the element 11, is a link lo having a pivotal connection 17 and adapted to pass through a suitable guide 18. An elastic member '19, such as a spring, surrounds the link 416 between its pivot 4T and the guide 41S and tends normally to move the scraper member -l-1 about its pivot 42 in a direction toward the dian'ietric center of the element, so that when the carcass is passed into the element 11, the members `l1 will be moved about their pivots in the opposite direction and against. the stress of the elastic member L19 so as to hold the scraper blades 1J- yieldingly against the carcass and in constant contact therewith, so that when the elements 11 are rotated, the carcass being supported by the adjacent elements 12, it will be manifest that the scraper blades 43 will travel around the carcass in contact therewith, and will have a wiping or scraping action on the carcass at all times.

Any number of these scraper members ll may be provided in each of the elements '11, and it will be manifest that when the carcass is passed between these members l1 so as to be surrounded thereby, the members 41 will not only compensate the varying sizes of the carcass, but the speed of rotation of the cleaning elements about the carcass increases in proportion tothe size, of the carcass, because the larger the carcass, the further the scraper elements will be forced toward the periphery of the element 11, whereas a smaller carcass will permit thi` scraping elements to be moved nearer the center of rotation of the element.

Thus it will be seen that the elements l2 will operate as the feeding elements and will also intermittently rotaie the carcass during its passage through the machine, and inasniuchas the' lower portion of the elements 11 are disposed to stand below the lower portion of the elements 12, it will be manifest that the scraper elements will be relieved of the weight ef supporting the carcass during its passage through the cleaning element, as the distance between the bottom of the clements 12 and the bottom portion of the next adjacent element 11 is suiiicieniV te permit ol such an action.

The carcass after it has passed through the elements 11 and 12 will be discharged therefrom by the ibs 39 on the last element 12 onto n suitable support or table 50 (ser, Fig. 2i from which it may be removed in any suitable manner.

During the passage of the carcass through the machine, and while the hair is being scraped therefrom by the scraping members a supply of water is being delivered into the elements, preferably from a pipe 5l which is arranged in a suitable position ailjacent the peripherie@` the elementsv 11. 12 and is provided with nozzles` a2 which are Sli lid.

i' ribs 40.

Lex/aies preferably adapted to extend into the space betiveen the proximate lateral edges of adjacent elements 11 and l2, the latter' being held spaced from each other a suitable distance to permit the nozzles to project ithereinto; s y i The pipe 51 receives its supply from the tank 53 and for that purpose, a suitable pump 544 may be provided. This pump has communication with the tank 53 to draw the .Water therefrom and force the saine through a` suitable pipe 55 into the pipe 51,a valve 56 being provided, if desired, for controlling the flow ofivater through the pipe 55.

The hair as -it is scraped from the carcass and the Water which is discharged intothe elements l1, will pass out of fthe elements through the openings l5 and also between the adjacent elements and will be collected in any suitable'mannerfsuch as iin a trough arranged to extend beneath the elements, and this trough is provided with a perforated bottom58. The troughis arranged above the tank 53 so that the Water Will be discharged back into the tank and the ha'ir will be collectedv upon the perforated bottom of the trough 57. Anysuitable means may be provided for removing the collected hair, such for instance, as a suitable cou veycr 59 having flights 60 connected with the conveyer and -movable over the perforated bottom of thetrough, so` as to scrape the hair from the bottom of the trough and deliver the saine out of the end of the trough. The conveyor 59 is adapted to be operated from the shaft u37d of the pulley 37 by means of asprocket chain `61a passing over a sprocket 62 on the shaft 37a and a similar sprocket 63 on `the shaft 64k of the pulley 65 over Which the conveyer passes, `and which shaft 64- is mounted in suitable bearings 65 on the frame of the machine. With this improved construction it Will. bc manifest that the carcass will `be sub- .jected to a Vcontinuous scraping or wiping action by the scraper blades lwhich latter remain; `in constant engagement With the carcass during Vits passage through the scraper element, and it Willbe also manifest that all parts of the carcass Will be engaged b i the sera er elements the carcass bein()- advancedthrough the machine Vby the ribs 49 and. will be given an intermittent rotation" during such While the preferred form of construction hasybeen hereinV shoivn and described, itis to be understood that many changes may be inadeinthe designand in theispecific ar-I rangement of `the various parts within the scope ofthe claims `vvithoutdeparting from thespirit of this invention.
